KiCad 10 Symbol, Footprint & JLCPCB Lookup Reference

Command-line and Python patterns for discovering exact KiCad 10 symbols, pin numbers/names, .pretty footprints, and live JLCPCB/LCSC catalog part numbers.

1. Four-Step Programmatic Discovery Workflow

flowchart LR
  S1["1. search('keyword')<br/>Find KiCad Symbol"] --> S2["2. show('Lib', 'Part')<br/>Verify Pin Numbers & Types"]
  S2 --> S3["3. search_footprints('pkg')<br/>Get Lib:Footprint String"]
  S3 --> S4["4. jlcpcb_search.py<br/>Verify Stock & Basic/Ext Class"]
Verify every symbol, pinout, footprint, and LCSC part number programmatically before wiring a subcircuit.
Interactive discovery commands (Terminal / Python) 
# 1. Search symbols, inspect pinouts, and search footprints via .venv/bin/python

# 2. Query live JLCPCB/LCSC stock, Basic vs. Extended feeder status, and pricing
